Gardaí are appealing for witnesses to two fatal shootings in Dublin last night.

A man is being questioned over the death of a woman in her 60s who was shot dead at her home in Killinarden in Tallaght. Gardaí arrested the man at the scene yesterday.

The dead woman's daughter, who is in her mid 30s (earlier information that she was in her 20s has been corrected by gardaí), received non-life threatening gunshot injuries during the attack. She is being treated at Tallaght hospital.

An injured man was arrested at the scene and taken to Tallaght Hospital for treatment. He has since been released from hospital and is being questioned in Tallaght garda station.

Just a few hours later, in an unrelated incident, a man in his 40s was shot dead in the Lucan area of Dublin.

Gardaí are appealing for witnesses to the shooting at a house on Earlsfort View at 7pm yesterday.

Crime Correspondent with the Irish Mirror Cathal McMahon said there may be a link with last week's shooting of John Gilligan.

"Gardaí will look at the shooting in Lucan and the shooting of John Gilligan and see whether there is any connection between them. We know that John Gilligan was known to the victim," he said.

A burnt-out car has been located in Glen Vale, Lucan. Gardaí are investigating the possibility that this may be involved in the Lucan shooting incident.
